If you want to harvest textiles, you must be raiding a dungeon with complexity level 4+. Without a gatherer ring, a maximum of five pieces could be harvested from a single plant.

Textiles cannot be grown, but they can be found from complexity 4 onwards. Simply harvest any that you see, gain Farming experience and use the resulting textile at a spinning wheel to make material that can be sewn into magic armour.

Farming patches can be used in dungeons of complexity 5 or 6. They can be found randomly in dungeon rooms, or can be constructed in the base room by replacing the Group Gatestone portal. This requires level 25 Construction, 5 Seeping elm branches and 5 Bathus bars. Creating the bars from Bathus ores requires level 10 Smithing. The branches and ores can be purchased from the Smuggler for a total of 11,500 coins.

Seeds can be gathered from monster drops or purchased from the Smuggler. Potato and mushroom seeds are used for growing food, while herb seeds are used to grow herblore materials.

It is possible to farm indefinitely in Daemonheim by combining Farming, Runecrafting, and Magic. To do this, 44 Runecrafting (91 allows you to make double runes), and 55 Magic is needed, along with any Farming level. 25 Construction and 10 Smithing are recommended.

To begin, pick up drops from the dungeon and sell to the Smuggler (or use High Level Alchemy on them) to make money.

Buy at least 5 Farming seeds from the Smuggler. Try to always use the seeds closest to your level, to get the best experience possible.

Use your remaining money to buy rune essence from the Smuggler. Make sure to leave enough money to buy about 100 rune essence, so about 5k coins should do. The higher your Runecrafting level, the less essence you need.

If players are able to grow, clean, and use featherfoil, it is possible to brew potions while still turning a profit, or at least losing only a small amount per cycle. The obvious benefit is gaining more Herblore experience. E.g., making Cure potions:

This results in breakeven if 4.9 herbs per patch are obtained, on average. Higher level seeds can give substantially higher herblore experience, but will give a loss per cycle, eventually depleting the player's funds.

Players who like this way of training may find it advantageous to search for two rooms next to each other with a farming patch in each. Farming two patches at once and alching the herbs all at one time is a more efficient way of doing this and significantly cuts the downtime waiting for herbs to grow.

This method will (in theory) allow a player to farm in Daemonheim at any level for any amount of time. The only limiting factor would be getting bad harvests of herbs. As long as the ring of kinship is set on at least level 1 Gatherer, this should not be a problem.
